ooooh :wracks brain: I'm pretty sure we've had this question before. I'm also 90% sure that the answer was that no, those sorts of works wouldn't be eligible for this challenge. Of course, it all depends on the particular story. Stories set in Arthurian times that are about original characters? Perfectly fine. Something specifically about Lancelot and Guinevere? Not eligible. The main character(s) have to be original and not based off any existing universe or mythos. Sorry!
